Your teenage daughter is supposed to be doing homework, but you catch her chatting online. She tells you that she’s talking about the math test tomorrow. Before your eyes start rolling, listen up: teens are using social networking sites for more than just gossip, according to a new study by the National School Boards Association.

The students who took part in the online survey, aged 9 to 17, said they spent almost as much time on social networking online as they did watching television. And it is what these kids are talking about online that is causing such a cheer: education. Of the students who took part in the study 60 percent reported that some of the most popular social networking topics were college planning, learning outside of school, careers, and schoolwork. They also reported posting writing and art projects that might have nothing to do with schoolwork.

Ann Flynn, director of education technology for the National School Boards Association, says incorporating (合并) social networking tools into educational curriculum (课程) is the way forward. Flynn says a school in Cleveland, Ohio is posting students’ book reports on a blog for students of their own ages, parents and other teachers to read and comment on. “If someone reacts other than the teacher, a child is much more likely to take an assignment seriously,” Flynn says.

Not only students but also parents can benefit. Now parents can go online and know what the class is doing. So, next time your child says her blog is educational, get curious, sit down and check out the blog with her. You might just learn something new yourself.
